Ubuntu 20.04 Server install from USB - Sorry there was a problem completing the installation

Question

New NUC10 (BXNUC10i5FNH4) with no operating system and downloaded a 20.04 Server ISO from Ubuntu. I used UNetBootin from https://unetbootin.github.io/ on Windows 10 to make a bootable USB stick for the 20.04 installer.

During the installation and after asking for my username and password, it displays an offer to install OpenSSH just before barfing with the sorry message (without waiting for my response to the OpenSSH offer) and splashes a Python traceback indicating a problem with subiquity.

I tried again with a 18.04 Server SIO to get the same error at a slightly different place but somewhere around where Heroku could be selected as an installation package (according to the Python traceback on 18.04)

I guess it is the new hardware and I'll be stuck until NUC10 is supported.

Can anyone help?

Solution 1

I downloaded Universal-USB-Installer-1.9.9.0.exe and that successfully converted the 20.04 server ISO into a bootable USB stick. In step 1 I selected Try Unlisted Linux ISO from the bottom of the drop-down list then browsed for the 20.04 ISO and from there it was plain sailing.

_{Answer moved here from OP's question.}

Solution 2

For me (on an unbranded PC with Celeron 3865U) none of the solutions here worked. Tried rufus, unetbootbin, universal usb. All lead to same problem. Also 18.04 throws the very same error. Eventually I got around this by installing 16.04 and upgrading to 18.04 and finally to 20.04.

In my case, I solved the problem by making the bootable usb sticker in "dd" mode using rufus

Avoid dual-boot +++ Dual-boot can be buggy - anyway it is a difference if you create *.iso with installed Linux or with wingoofz whatever version.

selecting 'Unlisted Linux ISO' did not work for me. So I tried 'Unlisted Linux ISO (GRUB)' in the mentioned application and it worked like a charm
